(10) For the purpose of calculating entitlement to any benefit under the legislation of Ireland in accordance with Articles 14 to 29, any insurance periods completed under the legislation of Jersey shall be converted to contribution weeks completed under the legislation of Ireland as follows:
The competent authority of Jersey shall—
(a)in the case of a quarterly contribution factor, multiply the factor achieved by a person in a quarter by thirteen; and
(b)in the case of an annual contribution factor, multiply the factor achieved by a person in a year by fifty-two.
The result shall be expressed as a whole number, any remaining fraction being ignored. The number of contribution weeks so calculated, subject to a maximum of the number of weeks during which the person was subject to that legislation in a quarter or in a year, as the case may be, shall be treated as if they were contribution weeks completed under the legislation of Ireland.
